I have a 2007 Pontiac torrent that I've had for 8 years. Within the last year I've been having trouble with the key getting stuck in the ignition. After several seconds and several jiggles I've always been able to get it out. Well this morning the key would barely go into the ignition yet I could still start it and drive it. This is the first time I've had this problem. Is this going to be an easy fix or will it need to be replaced?
